Patent DE-19852584-A1 (DE)
Inventor: THUENEMANN ANDREAS
IPC: D06M15/00
Filed: 1998-11-14
Abstract: The invention relates to an aqueous composition for the production of low energy coatings, and to methods for the production of said composition and a corresponding coating. An aqueous collodial dispersion with colloid particles containing polyions of an electrolyte and an ionic fluorinated surfactant are used, whereby the ions of said surfactant have an opposite charge to the polyions of the electrolyte. The polyions and at least one part of the surfactant ions form complexes contained in the colloid particles and the stochiometry of the dispersion in relation to the charge of the polyions and surfactant ions ranges from 1:1 and 1:1.5. The dispersion can be produced by means of a method that comprises the following steps: a homogeneous mixture of one or more ionic fluorinated surfactants and water is formed and an aqueous polyelectrolyte solution is incorporated in a slow and intensive manner. Coatings can be produced by applying the disperson in the form of a liquid layer to the surface that is to be coated and drying. The colloid dispersions are suitable for the production of anti-adhesive layers covering fibers and for the production of an improved slip coating.

Abstract: The invention relates to a method for regulating the transmission power in a radio communication system, in which base stations and subscriber stations are connected by a radio interface. A subscriber station receives transmissions from a base station and determines a measured value therefrom for regulating the transmission power. According to the invention, the subscriber station links a service-dependent transmission power value to the measured value to obtain a regulating value and transmits said regulating value to the base station. The base station uses the regulating value to regulate the transmission power. The invention is characterised in that a reference to the desired service is immediately established, thus allowing the base station to calculate and regulate the necessary transmission power for the subsequent transmissions without further requests.

Abstract: Thermal processing of shredded plastic articles comprises heating with nitrogen-containing additive/catalyst mixture at to 350 - 600 degrees C in two stages. The gases produced in the first stage of carbonization are used to activate the carbon produced, after which they are burnt to heat the reactors used in the two stages. Method for thermal processing of materials containing polymers and cellulose, especially shredded articles, comprises mixing shredded waste plastic with a nitrogen-containing additive/catalyst mixture in an indirectly heated main reactor (1). Mixing is carried out using a mixing screw (13) while heating to 350 - 600 degrees C, so that carbonized material and gas are produced. The carbonized material is fed to a post-treatment reactor (2) where it is treated at the same temperature with the gas produced, further degassed, activated by the hydrogen in the gases, and fed via a perforated screw to a grinder (3). Here it is ground to the desired particle size, fed to a magnetic separator (9) to remove metal and then molded into active carbon pellets in a pelletizer (11). The gases are fed to a first washer (4), which uses water, and then to a second (5) which uses a calcium-containing solution. The purified gas is heated by heat exchangers (6a, 6b) and burnt in a burner (28) and/or pressure/heat coupling device to heat the main and post-treatment reactors. An Independent claim is included for apparatus for carrying out the above process.
